Al just needs somewhere to live, and he thinks he's found the perfect solution. 

He considers himself an unorthodox, and uninvited, housesitter, identifying when a property owner is going away and using the house in their absence. By the time they come back, he'll have moved on and they won't know he's ever been there. 

He assures us that he has his methods tuned to perfection - except that he's writing on the prison computer so something has clearly gone wrong. And so the story unfolds.

Al stumbled across three people who had the same notion of glorified squatting and, in a series of unfortunate events, they find themselves implicated in something much more serious altogether. 

It's brilliantly original, entertaining and gripping. Very good!
